"Ira was cordial and professional. He has practical experience and knowledge of residential energy audits. He was able to provide useful suggestions but not definitive solutions to issues. That may have been due to inaccessible interior walls. I am frustrated that a full written report that had been promised still has not been produced six weeks later."

"On Saturday afternoon my heat went off. Called Adem because he had done some minor work for me previously and I was satisfied. He came over Sunday morning (even though it was his day off), checked out the situation, and made recommendations. I called him several times on Sunday and he patiently answered all my questions. No pressure. I decided what to do, he showed up promptly on Monday morning with the new furnace, and by that afternoon I had heat again. He finished tying up remaining details of the job on Tuesday and will take care of the required permits for me. When cooling season begins, he'll get my AC up and running. I'm very satisfied with Adem's professionalism, expertise, and prompt response in restoring heat to my home just before temps plummeted into the single digits."

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

". the work was being done was  at best puzzling and cast a shadow over the entire experience. What makes this review diffulcut is that I want to give higher marks for the work that was done since we have not had any problems to date but the fact that even after they called to set up one last visit to tie up some remainig concerns they never showed up and this makes it diffulcult to have positive feelings. Questions about the supposedly HOME SURGE PROTECTION system and WARRANTY and how to handle any future issues regarding it have never been explained or paperwork supplied. When it is so hard to reach the boss it creates  an environment of distrust be it real or imagined.

"RC came out to service the hot water heater at my house in South Jersey last year. Even though it was an old unit, no one tried to coerce me into purchasing a new heater, which would have been out of my budget. They arrived in a very timely manner, the employees were knowledgeable and professional, and the problem was fixed immediately. I would recommend them to anyone!"

Energy Efficiency Auditing FAQs, answered by experts

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.
